SPEQIFTCATION'fQrming part of Letters Patent No. 249,449, dated November 15,1881,

Application filed September 24, 1881. No'model.l

To all whom it may concern:

Be it known that I, JOHN FREDK. BEHN, a

citizen of theUnited States, residing at Buffalo,

in thewcounty of Erie and State of New York, have invented certain new and useful Improvementsin Apparatus for suspending, Raising,

and. Lowering Electric Lamps; and I do herebydeclare the following to be afull, clear, and exact description of the invention, such as will enableothers skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to an apparatus for suspending electric lamps in streets, highways,

and halls; and has for its object to provide for s an easy and rapid raising, lowering, and adjnsting of the lamp, as well as the prevention of any swaying motion of the same when in a position, which might be caused by heavy winds; and tothis end my invention consists in a. frame or carriage suspended upon two or more parallel cables, pipes, or cords firmly stretchedor secured either to poles or to the curely ina socket upon the carriage, and as the carriage is moved upon its supporting-cables from its central position to either side the lamp will move downward in a diagonal path until it is at apoint where it is easily accessibleforrenewingofcarbons,cleaning,repairing,

&c. The positive and negative wires which supply the lamp with electricity may be connected therewith in any suitable manner; but

this forms no partof my invention.

In the drawings, Figures 1 and 2 are diagrams to illustrate. the application an d operation of my apparatus. a. Fig.3 is a front view of the carriage and lamp when in position. Fig. 4 is a side view of the same, and Fig. 5 is-acentral transverse section of Fig. 3.

Referring'to the drawings, a a in Figs. 1

, and2represeut in section the buildings from i which the lamp is suspended.

b b are two parallel metallic cables, pipes, or cords, which are firmly secured at their ends to the wall of the buildings a a, or they may be secured to poles where there are no buildin gs to be thus utilized. These cables or cords, as shown in Fig. 1, are secured one above the other in a vertical plane, and serve to support This carriage consists of the lamp-carriage. the frame 0, in which are located the upper pulleys, 0 c, and lower pulleys, c 0?. The pulleys c 0, located at the top of the carriage, run upon the upper cable, b, and the pulleys c c at the bottom of the carriage run upon the lower cable, I). These parallel-cables, being placed one above the other, serve to keep the carriage always in a vertical position, and the pulleys allow it to be easily moved back and forth thereon. c c, and midway between them, is placedthe smaller pulley 0 which bears against the upper cable, I), on its lowerside, and serves to keep it in contact with the pulleys c c.

The lamp-carriage is moved back and forth upon its supporting-cables by means of the cord d, which is secured at its ends d d to the sides of the carriage, and runs over certain pulleys in the following manner: Beginning at the right-hand side of the carriage, the cord at extends parallel with the supportingcablesto the pulley (1 upon the side of the building; from thence it passes over such pulley down to and around the pulley 61 secured to the side of the building and located at a convenient distance from the pavement, and from thence itpasses up to and around pulley d andthrough the carriage,across to and around the pulley d attached to the opposite building, and then to the carriage, where it is secured.

It will be seen that the carriage can. be moved back and forth upon its supporting-cables b I) by operating the cord at at its lower turn, where it passes around the piilleyd which is placed so that it can be reachedanfd operated from the street by means of aladder. At the top of the lamp-carriage, and at oneside thereof, is located the pulley e, and at the bottom of the carriage, on the same side as the pulley e, and

extending at right angles to the carriage, is the plate f, with a central opening, f, therein. Surrounding this opening, and extending up wardly, is the socket f in which the top projection, g, of the lamp h rests when the lamp is Just below the upper pulleys in position. At the top of the projection g is secured the cord or wire k, which passes over the pulley e, thence parallel with the pulley b to and over the pulley e, and down the side of the building to the button or staple l, where it is secured.

It is evidentthat the cord is might be secured directly to the building where the pulley e is located, but my present arrangement enables me'to lower the lamp from any point on the supportin g-cables, should the carriage from any cause fail to operate.

To compensate for the weight of the lamp, the pulley e, and the platef, with its socketf which, it will be observed, are all placed upon one side of the carriage, I have provided a counterweight, m, adjustable upon the rod m and adapted to be held securely in place by the set-screw m By adjusting this weight as occasion requires any undue strain or wear upon the cables I) I) is avoided, and the lamp and its carriage held in a vertical position.

The operation of my device is as follows: When the lamp is-in position, as shown in full lines in Fig. 1, and it is desired to lowerthe same, it isonly necessary to move the carriage toward thebuilding by operating the cord d. As the carriage is moved the slack of the cord 70 is drawn down by the weightof the lamp, which: moves out of its socket in the carriage and downwardly in a diagonal direction, as'illustrated in dotted lines in Fig. 1, toward the building, where access may be had to it for renewing the carbons, cleaning, repairing, 850. By moving the cord d in the oppositedirection the lamp is caused to ascend in a diagonal path until its projection g rests in the socket f in the carriage. I j I It will be observed that by my improved apparatus the lamp ismade easily accessible at all times, and the arrangement of the supportin g-cables upon whichthe carriage travels precludes the possibility of any swaying motion of the lamp when in position. It will also be carriage adapted to move back and forth upon such cables or pipes, and suitable cords and pulleys for operating the carriage upon the cables and raising and lowering the lamp to and from the carriage, substantially as shown and described.
